Abstract: The main function of the pavement is to carter the need of walk traffic while not to affect vehicle flow on the roads. When the pavement is occupied but some room stil left for pedestrians to cross, the room for pedestrians to cross is becoming smaller, the walk of the pedestrians is restricted, the speed is becoming lower and the satisfaction for the pedestrians is reduced. When the pavement is totally occupied, pedestrians use the outboard lanes to make a detour round the occupied pavement. In this situation, pedestrians collide with vehicles and vehicles endanger the safety of pedestrians . They will form a sense of fear and their travel safety will not be guarantee. When the pavement is occupied absolutely, pedestrians occupy vehicle lanes. Thus the passing capacity of the road is reduced; the speed of vehicles becomes lower and the travel delay increases.

Key words: pavement, be occupied, effect, pedestrians, vehicles
